The jet is custom-fitted with an office and a cabin with game consoles, music systems, satellite television and wireless communication, the report said.

It also has a master bedroom, a bathroom with a range of showers and a bar with mood lighting. The newspaper said Airbus sources had confirmed the sale and the jet had arrived at New Delhi's airport and would be brought to Mumbai soon.

But it has also drawn criticism as an edifice to vulgarity in a country where hundreds of millions live in crushing poverty.
